HIRSHON:
These are the street sounds of Pittsburgh. They were collected by city residents and added to an interactive, online map of the city being developed at Carnegie-Mellon. People can add anything to the map, says designer Carl DiSalvo, like the locations of thier favorite street vendors or an image of the place they fell in love.

CARL DISALVO (Carnegie-Mellon):
The idea is that all of this data can be shared and the idea is that it can be layered on top of one another to create a richer picture that you could ever create yourself.

HIRSHON:
The result is a map that charts the city by what its residents think is important, instead of by official statistics. DiSalvo hopes it will help people get to know their city in a new way.
